A Brief Overview of Multifractal Time Series

Cardiac Dynamics

Luís Amaral

In the Exploring Patterns in Nature
tutorials, we observed how disordered, irregular, fractal patterns can
be quantified in terms of their spatial fractal dimension. Here we
study fractal (and multifractal) patterns of a different sort:
patterns in time.

This overview attempts to give a short operational review of
multifractality in time series. For this reason, formal definitions
and derivations are not discussed; see Refs. 1-4 for more in-depth
reviews.
